When Boruto fought Boro in another dimension to rescue Naruto, who had been sealed in a jar by Jigen, some interesting moments provided insight into the Kara organization’s relationship with Boruto.

During the battle, Boruto was weakened after inhaling a deadly virus-infused black mist released by Boro. While Boruto was incapacitated, Boro approached him and unexpectedly expressed his gratitude. According to Boro, thanks to Boruto, the time constraint that had previously limited Kara’s grand plan was no longer an issue.

This statement confused Boruto, as he had no idea what Boro meant. However, Boro’s words had a strong underlying reason closely tied to Kara’s ultimate scheme.

Here is the explanation of why Isshiki chose not to eliminate Boruto and why Boro thanked him.

# Why Boro Thanked Boruto

Before the battle between Boruto and Boro took place, the Kara organization was in a state of upheaval. After Delta returned to Kara’s base following her defeat at the hands of Naruto, she delivered some shocking news to the Inner members of Kara. Delta revealed that someone else possessed a genuine Karma mark besides Jigen and Kawaki. This revelation shocked the entire Inner Kara, including Code.

Initially, Code, who had conducted an investigation on Naruto following his battle with Momoshiki, assumed that Naruto or Sasuke was the one who bore Momoshiki’s Karma. However, he did not find any signs of Karma on Naruto’s palm. Delta clarified this assumption by revealing that the true bearer of Momoshiki’s Karma was none other than Uzumaki Boruto.

Even Jigen himself was surprised that Momoshiki had managed to implant his Karma into Boruto’s body as a vessel moments before his death. The revelation that Boruto was the heir of Momoshiki’s Karma was crucial information for Kara, especially for Boro.

Although Boro was eager to see the realization of the Infinite Tsukuyomi plan, he felt relieved knowing that Boruto had become Momoshiki’s vessel. With Boruto’s existence, Kara no longer needed to rush their primary objective, as the Karma embedded in Boruto’s body provided them with additional time to prepare.

This is why Boro expressed his gratitude to Boruto.
